I the e gt In operating thedevice of this invention, a pie Figure 1 isa slde vlew, partly brok newa of pan 34, containing the ingredients of a pie and the p l crlmpmg machme 0f h inVen" having atop crustplaced thereon, is securely t1on. placed inthe pie pan Ill. The block H is then Figure 2 is arbottom plan view of one of the longitudinally and verticallyadjusted by means crimping gears taken on the line 2-2 of Fig- .ofthehan-dwheels I79 and 20, so that the crimp- 11ml, h t ling surface 24 of thecrimping wheel 21 engages 55 the periphery of the piecrust, and the crimping surface 28 of the crimping wheel 26 engages the top portion of the piecrust at the periphery thereof. The block I! is so adjusted in relation to the piecrust that a slight-pressure is exerted on the top and at the side on the periphery of the same by means of the crimping surrfaces 24 and 28, respectively.

The shaft I2 is then rotated, turning the pan carrier It] in which the pie pan containing the pie has been placed. The engagement of the piecrust with the crimping surfaces 24 and 28 of the crimping wheels 2| and.26, respectively, rotate the same, since the wheel 26 is mounted freely about the screw 21 and the wheel 2| is,

adapted to revolve freely on the screw 22. The crimping wheel 2|, as it revolves, presses the periphery of the piecrust inwardly and the orimping surface 28 of the crimping wheel 2 5presses downwardly on the piecrust which seals the top piecrust to the bottom piecrust.

Since the rounded surface 33, on the wheel 2|, between the crimping teeth 32 communicate with the space between the gear teeth on the bevelled gear surface 23 and the rounded surfaces 3|, on

the wheel 26, communicates with the space between the teeth on the bevelled gear portion 28 any dough from the piecrust which adheres to the rounded surfaces 33 and 3| on the wheels 2| and 26, respectively, will be passed through the rounded surfaces between the teeth on the crimping wheel and the space between the gear teeth on said wheel and out over the top ofthe crimping wheels.

The plate, I to which the pie pan carrier is fastened may be mounted on a revolving platform which will deliver the pie pan carrier to such a position that the piecrust engages the crimping wheels 2| and 26. The pie pan carrier is then revolved, 'turningthe crimping wheels 2| and 26 whichcrimp the piecrust.

It is apparent that the specific illustrations shown have been given by way of illustration and not byway of limitation, and that the structure above described issubject to wide variation and modification without departing from the scope or intent of the invention, all of which varia- ,tions and modifications are to be included within the scope of the present invention.

4. In a piecrust crimping machine a rotatable pie pan carrier, a mounting above said pan carrier, a supporting block longitudinally and vertically adjustable in said mounting in relation to said pan carrier, a crimping wheel rotatably mounted on the bottom of said block the axis of also having gear teeth thereon, the rounded surfaces between the teeth on saidcrimping surface communicating with the space between the said gear teeth, and a second crimping wheel rotatably, mounted on a side adjacent to said firstmentioned side of the supporting block, the plane of the axis of rotation of said second wheel being at an angle of less than 90? to the plane of the axis of the first-mentioned wheel and intersecting the axis of the first-mentioned crimping wheel and the axis of rotation of said pan carriensaid second wheel having a. toothed crimping surface adapted to engage the top of the piecrust about the said periphery and having a rounded surface between the teeth said second-mentioned crimping wheel also having gear teeth thereon enmeshed with the gear teeth on said first-mentioned wheel, the rounded surfaces between the teeth on said.- crimping surface communicating with the space between the said gear teeth.

5. In a piecrust crimping machine a rotatable :pie pan carrier, a mounting above'said pan carrier, a supporting block longitudinally and vertically adjustable in said mounting in. relation to said pan carrier, a crimping wheel rotatably mounted on the bottom of said block the axis of rotation of said wheel being in a plane parallel to the plane of the axis of rotation of said pan carrier, the axis of said wheel being parallel to the axis of said pan'carrier, said wheel having a toothed crimping surface adapted to engage the ariphery of the piecrust and having a rounded lrface between the teeth said crimping wheel so having gearteeth thereon the rounded sur- LCBS between the teeth on said crimping surface )mmunica-ting with the space between the said ear teethgand a second crimping wheel rotatoly mounted on a side adjacentto said first- Lentioned side of the supporting block, the plane E the axis of rotation of said second wheel being t an angle of less than 90 to the plane of the xis of the first-mentioned wheel and intersect- 1g the axis of the first-mentioned crimping wheel nd the axis of rotation of said pan carrier, said JOHN ROMAN OFF.
